Flowers:
Inflorescence a narrow panicle 10-20 cm long, the branches short, appressed; spikelets closely (2-) 3- to 6-flowered, 10-17 mm long; lower glumes 6-8 mm long, 5-nerved, the upper ones 8-10 mm long, 7-nerved; lemmas strongly fringed with fine hairs on the lower halves, especially along the margins, obscurely 9- to 11-nerved, rounded or with shallow notches at the tips, about 10 mm long, inconspicuously awned, usually with fragile awn tips 0.5-3 mm long; anthers (3) 4 mm long.
